When will the Fed hike interest rates?

NEW YORK (CNNMoney) -- Federal Reserve officials are more talkative than ever, making roughly 20 public appearances this week.

And while all the noise coming from "hawks" and "doves" could give you a case of Fed fatigue, there's one point both sides are hammering home: Forget the central bank's forecast for raising interest rates in 2014. At this point, anything could happen.

Instead, he said, his colleagues may have to raise rates as early as this year.

"I see no need for additional accommodation at this time, and I believe that conditions will warrant raising rates well before the end of 2014," he said in remarks in White Bear Lake, Minn. on Thursday afternoon.

Separately, Dallas Fed President Richard Fisher piped up earlier this week, saying business leaders are telling him they too are concerned the Fed's stimulative policies could spark rapid inflation.

So far that hasn't happened. Currently, the annual inflation rate is hovering around the Fed's goal of 2%.

They're less concerned with inflation and think the Fed should continue to support the economy through loose monetary policy.

Janet Yellen, second in command to Fed Chairman Ben Bernanke, said Wednesday that the Fed may have to keep interest rates near zero not only through 2014, but until late 2015.

She stressed many of Bernanke's recent points: the job market remains "far from full employment" and the economy still has many risks looming on the horizon including a still struggling housing market, tighter fiscal policy and worries about global growth.

Yellen even hinted that if the economy were to take a turn for the worse, further easing might be needed.

"Considerable uncertainty surrounds the outlook, and I remain prepared to adjust my policy views in response to incoming information," she said.

What Yellen says should be taken seriously. She's part of the Fed's dovish camp, which currently accounts for a majority of the votes on the central bank's policymaking committee. That group also includes Bernanke, New York Fed President William Dudley and the three other Fed governors.
